Shock Torque Specs Confirmation

[ACK]

Was reassembling and torquing down the rear suspension on the C10 and just can't get over the torque specs for the shocks ... 130-150 ft. lb. for the upper eye and 55-75 ft. lb. for the lower. The upper mounts were pinching the heck out of the bushings and I still had a ways to go, so I stopped and moved on because it just didn't feel right. I know they're book torque specs, but would feel better if I heard from others confirming they ratchet down that much on the shocks.

Ya that does "seem" rather high but thats what the chassis torque specs show.
1/2" grade 8 fasteners torque at 90 foot pounds and 5/8" grade 8 are 159/180 ft lbs. So I guess they're using the 5/8 size fasteners?
Maybe someone in engineering can assist.

I think that spec is for the big nut on the back side of the upper shock mount stud and no the nut that goes on the shock end.

Thanks for the replies. I started cranking down to spec and it looked so bad I backed off and tightened all to 45 ft. lb. I did a little reading and it appears there's 2 bushing styles and I'm pondering if the previous owner installed shocks with the non-stock style bushing, hence the brackets pinching like heck.

Yep i guess the torque is so high because of the bolt size.
